随机需求下供应链融资机制和策略研究

Study of Financing Mechanism and Strategy for Supply Chains with Stochastic Demands

研究资金约束下二级供应链的融资决策问题.考虑到零售商不同的销售情况对偿还能力的影响,分别建立随机需求环境下的分散式和集中式决策模型.进一步利用回购企业对分散式决策模型进行协调,并通过数值试验和相关参数的灵敏度分析验证了理论结果.结果表明:回购契约能够协调供应链;在回购契约下,零售商会增加订购量来满足顾客需求,供应链利润得到提高;通过改善各参数取值,可以提高供应链的效率.

This paper studies the financing decision of a two-echelon supply chain with capital constraint.Considering the impact of the retailers’different sale conditions,the paper proposed the decentralized and centralized models under the stochastic demand environment.We used a buy-back contract to coordinate the decentralized model.Finally we conduct a sensitivity analysis to test the impacts of several key parameters on the supply chain models.The results show that the buy-back contract can coordinate the supply chain;Under the buy-back contract,the retailer increases the order quantity to meet customers’demands and the supply chain’s profit is improved;The performance of the supply chain may be improved effectively by changing several key parameters.
